+
+ * src/system.h: We don't need nor want bcopy.
+ Throw away MS-DOS crap: we don't need getpid.
+ * configure.in: We don't need strndup. It was even causing
+ problems: because Flex includes the headers *before* us,
+ _GNU_SOURCE is not defined by config.h, and therefore strndup was
+ not visible.
+ * lib/xstrndup.c: New.
+ * src/scan-skel.l: Use it.
+ Be sure to initialize yylval.muscle member when scanning a MUSCLE.
+ * src/parse-skel.y: Use %directives instead of #defines.

+ * src/output.c (output_parser, output_master_parser): Remove, dead
+ code.
+ * src/output.h (get_lines_number, actions_output, guards_output)
+ (token_definitions_output): Prototype them.
+ * src/parse-skel.y: Add the license notice.
+ Include output.h and skeleton.h.
+ (process_skeleton): Returns void, and takes a single parameter.
+ * src/scan-skel.l: Add the license notice.
+ Include skeleton.h.
+ Don't use %option yylineno: it seems that then Flex imagines
+ REJECT has been used, and therefore it won't reallocate its
+ buffers (which makes no other sense to me than a bug). It results
+ in warnings for `unused: yy_flex_realloc'.

+ * src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
+ (MUSCLE_INSERT_PREFIX): Move from here...
+
+ * src/bison.hairy: Add a section directive. Put braces around muscle
+ names. This parser skeleton is still broken, but Bison should not
+ choke on a bad muscle 'syntax'.
+ * src/bison.simple: Add a section directive. Put braces around muscle
+ names.
+
+ * src/files.h (strsuffix, stringappend): Add declarations.
+ (tab_extension): Add declaration.
+ (short_base_name): Add declaration.
+

+ Adjust all dependencies.

+ Renaming yylval but not yylloc is not consistent. Now we do.
+

+
+ * tests/regression.at (Web2c Actions): Blindly move the actual
+ output as expected output. The contents *seem* right to me, but I
+ can't pretend reading perfectly parser tables... Nonetheless, all
+ the other tests pass correctly, the table look OK, even though the
+ presence of `$axiom' is to be noted: AFAICS it is useless (but
+ harmless).
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * src/reader.c (readgram): Don't add the rule 0 if there were no
+ rules read. In other words, add it _after_ having performed
+ grammar sanity checks.
+ Fixes the `tests/regression.at (Invalid input: 1)' Failure.
+
+2001-12-29 Akim Demaille <akim@epita.fr>
+
+ * tests/regression.at (Web2c Report): Catch up: the rule 0 is now
+ visible, and some states have now a different number.

+
+ * src/reader.c (readgram): Bind the initial rule's lineno to that

+ * tests/regression.at (Rule Line Numbers, Unresolved SR Conflicts):
+ (Solved SR Conflicts): Adjust rule 0's line number.

2001-12-29 Akim Demaille <akim@epita.fr>
Fix the `GAWK Grammar' failure.
* tests/regression.at (Rule Line Numbers): Adjust: state 0 does
have a reduction on $default.

* src/derives.c (print_derives): Be sure to use `>= 0', not `> 0',

Fortunately, now, the $axiom is no longer nullable.
